On the DRM System Settings window the Suppress Date Change Dialog at Midnight has two choices, (1) Don’t Change Date and (2) Change Date.
If you check the box to Suppress Date Change Dialog at Midnight, then click the ‘Change Date’ radio button and click OK, when you open the System Settings window back up again, the radio button for ‘Change Date’ becomes unchecked.
This issue has been found in GP 2010.0.5 and GP 10.0.14.
This is a bug and has been submitted to CRM for fixing in a future build. The workaround is to click the ‘Change Date’ radio button, then click OK. Once the window is closed, do not re-open the window.
